A component which is not illustrated such as a digital television broadcasting receiving function, an e-money payment function, or the like may be further added.

FIG. 3 is a functional block diagram illustrating the handheld device 1 of the present embodiment. Functional blocks of the handheld device 1 are controlled by the control unit 1010.

The control unit 1010 operates on the CPU 101 with which the handheld device 1 illustrated in FIG. 2 is equipped, includes a user authentication unit 1011, a state determination unit 1012, a lock control unit 1013, an application start unit 1014, and the like, and controls a memory 1030, a static biometric information acquisition unit 1110, a dynamic biometric information acquisition unit 1120, a communication unit 1310, or the like based on an instruction given from a user interface 1040 such that the static biometric information and the dynamic biometric information are acquired, stored, and compared, the handheld device 1 is locked or unlocked, or an application starts.

The user interface 1040 is configured with the operation device 104, the audio input device 141, the audio output device 142, the video input device 151, the display device 152, and the like which are illustrated in FIG. 2, and presents the user with various kinds of information and transfers the instruction of the user to the control unit 1010.

The static biometric information acquisition unit 1110 is configured with the fingerprint sensor 111 and the like which are illustrated in FIG. 2 and detects a fingerprint and the like which are the static biometric information of the user who uses the handheld device 1.

The dynamic biometric information acquisition unit 1120 is configured with the heart rate sensor 112, the blood pressure sensor 113, the temperature sensor 114, and the like which are illustrated in FIG. 2, and measures the heart rate, the blood pressure, the body temperature, and the like which are the dynamic biometric information of the user who wears the handheld device 1.

The communication unit 1310 is configured with the mobile communication device 131, the LAN communication device 132, the short-range wireless communication device 133, and the like which are illustrated in FIG. 2 and performs acquisition of an application and transmission reception of various kinds of data.

The memory 1030 is configured with the memory 103 and the like which are illustrated in FIG. 2, and stores static biometric information 1031, dynamic biometric information 1032, an application 1033, a permission level table 1034 which is a table of levels at which applications are permitted to start, and the like, in addition to the program and various kinds of setting information for controlling the handheld device 1.

The static biometric information 1031 is, for example, a fingerprint of the authorized user acquired through the static biometric information acquisition unit 1110. Before the handheld device 1 is used, the static biometric information of the authorized user is registered in advance.

The dynamic biometric information 1032 is, for example, the heart rate, the blood pressure, and the body temperature of the user acquired through the dynamic biometric information acquisition unit 1120. When the handheld device 1 is used, for example, the dynamic biometric information of the user in the normal state is measured and registered.

The application 1033 is an application program acquired through the communication unit 1310 or an application program which is pre-installed. A plurality of application programs can be registered, and an application permission level can be registered in the permission level table 1034 in association with each application program.

The user authentication unit 1011 determines whether or not the user is an authorized user by comparing the static biometric information acquired through the static biometric information acquisition unit 1110 when the handheld device 1 is used with the static biometric information 1031. When the user is authenticated to be the authorized user, the lock control unit 1013 is controlled such that the handheld device 1 is unlocked.

The lock control unit 1013 is controlled by the user authentication unit 1011 such that the lock control unit 1013 unlocks the handheld device 1, and, for example, when the user interface 1040 is not operated for a certain period of time, the lock control unit 1013 locks the handheld device 1. Further, even when the state determination unit 1012 is determined to be in a sleep state, the lock control unit 1013 locks the handheld device 1.

The state determination unit 1012 determines the state of the user by comparing the dynamic biometric information acquired through the dynamic biometric information acquisition unit 1120 when the handheld device 1 is used with the dynamic biometric information 1032, and controls the lock control unit 1013 and the application start unit 1014. For example, when the user is determined to be in the sleep state, the lock control unit 1013 is controlled such that the lock control unit 1013 locks the handheld device 1. Further, when the user is determined to be in the normal state, all applications are set to enter a startable state, and when the user is determined to be in a stress state, applications that can be started are limited. Applications to be limited are registered in the permission level table 1034. A start permission level of each application may be decided in advance and may be registered by the user through the user interface 1040.

An application to be started is not limited to the application 1033 stored in the memory 1030, and an application on the network 6 may be started through the communication unit 1310.

FIG. 4 is a flowchart illustrating an application permission operation of the handheld device 1 of the present embodiment. This flowchart illustrates a process of performing the user authentication through the handheld device 1, checking the state of the user, and limiting an application to be started according to the state of the user. First, the static biometric information is detected, and the user authentication is performed. The static biometric information acquisition unit 1110 acquires the static biometric information, and the user authentication unit 1011 performs the user authentication as to whether or not the acquired static biometric information is identical to the static biometric information 1031 which is registered in advance by comparing the acquired static biometric information with the static biometric information 1031 (S401). For example, the fingerprint serving as the static biometric information is detected, the user authentication is performed, and when the detected fingerprint is determined to be identical to the registered fingerprint, the lock control unit 1013 unlocks the handheld device 1 (S402), and the application start unit 1014 permits a start of an application of the permission level 1 (S403).

For example, the application of the permission level 1 is an application that does not relate to information of the user him/herself and has no particular problem even when it is used by anyone else such as a clock application, a web browser, a map application, a camera application, a weather forecast application, a music application, a calculator application, a dictionary application, a game application, and a navigation application. The permission level of each application is registered in the permission level table 1034.

A display example of a screen of the handheld device 1 at this time is illustrated in FIG. 5A. The clock application, the web browser, the map application, the calculator application, and the dictionary application are the applications of the permission level 1 and thus are in the startable state, and the other applications have a different icon color which indicates that they are in the non-startable state.

The user authentication may be performed through any other biometric authentication such as a vein authentication, a face authentication, an iris authentication, or a retina authentication, in addition to the fingerprint authentication, and for example, when the handheld device 1 is worn on the wrist, the user authentication may be performed through the vein authentication for the part on which the handled device 1 is worn, so that a situation in which anyone else wears the handheld device 1 and pretends to be the authorized user can be prevented. Alternatively, the unlocking operation may be performed by inputting a passcode, and a pattern lock may be released by the trajectory of the finger.

Generally, there is no difference between a period of time in which the static biometric information for the fingerprint authentication, the vein authentication, the face authentication, the iris authentication, the retina authentication, or the like is acquired and a period of time in which the passcode is input, and a period of time taken until the application of the permission level 1 enters the startable state is about several seconds.

Then, the dynamic biometric information is detected, and the state of the user is determined. The state of the user is determined such that the dynamic biometric information acquisition unit 1120 acquires the dynamic biometric information, and the state determination unit 1012 compares the acquired dynamic biometric information with the dynamic biometric information 1032 that is registered in advance (S404).

For example, the heart rate, the blood pressure, and the body temperature which are the dynamic biometric information are measured in the normal state and registered in the dynamic biometric information 1032, the dynamic biometric information acquisition unit 1120 measures the heart rate, the blood pressure, and the body temperature, and when the heart rate, the blood pressure, and the body temperature are equal to or less than lower limit values in the normal state, the sleep state is determined. Further, for example, when the heart rate and the blood pressure are equal to or larger than upper limit values in the normal state, the stress state is determined, and a state which corresponds to neither the sleep state nor the stress state is determined to be the normal state.

Generally, a period of time in which the dynamic biometric information such as the heart rate, the blood pressure, the body temperature, the brain wave, or the amount of sweating is acquired is longer than a period of time in which the static biometric information is acquired, and a period of time taken until applications of permission levels 2 and 3 (which will be described later) enter the startable state is about several tends of seconds. For this reason, acquisition of the dynamic biometric information may start at the same time as when acquisition of the static biometric information starts, or the dynamic biometric information may be constantly acquired, and the state determination may be performed based on the biometric information obtained for previous 30 seconds.

First, the process is switched according to whether or not the state of the user is the sleep state (S405). When the state of the user is determined to be the sleep state, the handheld device 1 is locked (S410), and the process ends (the permission level 0). For example, when the user is asleep in a station, a park, or the like, although another person causes the handheld device 1 to touch the finger of the user and perform the fingerprint authentication, if the heart rate, the blood pressure, and the body temperature are equal to or less than the lower limit values in the normal state, the state of the user is determined to be the sleep state, and thus the handheld device 1 can be locked.

When the state of the user is determined not to be the sleep state, the process is switched according to whether or not the state of the user is the stress state (S406). When the state of the user is determined to be the stress stat, the applications of the permission levels 1 and 2 are permitted to be started (S407).

For example, the application of the permission level 2 is an application that relates to the user him/herself and is considered to have a problem when it is used by anyone else such as a schedule application, a mail application, a photo application, a telephone application, or an address book application. The application of the permission level 2 is an application which is considered to have no particular problem regardless of the state of the user when the user is the authorized user. A display example of a screen of the handheld device 1 at this time is illustrated in FIG. 5B. In addition to the fact that the applications of the permission level 1 are in the startable state, the schedule application and the mail application are the applications of the permission level 2 and thus are in the startable state, and the other applications have a different icon color which indicates that they are in the non-startable state.

When the state of the user is determined not to be the stress state (determined to be the normal state), all applications of the permission levels 1 to 3 are permitted to be started (S408).

For example, the application of the permission level 3 is an application that relates to information of the user him/herself and is considered to have a big problem when it is used by anyone else such as an e-money application or an online banking application. The application of the permission level 3 is an application which is considered to have a problem depending on the state of the user even when the user is the authorized user.

For example, when the user is panicked and unable to make conscious determination due to a bank transfer fraud or the like or when the user is coercive to perform an operation by another person, if the heart rate and the blood pressure are equal to or larger than the upper limit values in the normal state, the state of the user is determined to be the stress state, and the e-money application, the online banking application, and the like can be set not to be started.

FIG. 5C illustrates a display example of the screen of the handheld device 1 when all applications are permitted to be started. In addition to the fact that the application of the permission level 1 and the application of the permission level 2 are in the startable state, the e-money application and the online banking application are the applications of the permission level 3 and thus are in the startable state, and it is indicated that all applications are in the startable state.

Then, the process is switched according to whether or not a predetermined period of time has elapsed while the user does not perform an operation (S409). When a predetermined period of time (for example, 10 seconds) has elapsed, the handheld device 1 is locked (S410), and the process ends.

When a predetermined period of time has not elapsed, the process returns to step S404, and the process is continued. For example, when the state of the user is determined to be the stress state, and the application of the permission level 3 enters the non-startable state, if the state of the user returns to the normal state later, all applications enter the startable state. Thereafter, when the state of the user is determined to be the stress state again, the application of the permission level 3 enters the non-startable state, and when the state of the user is determined to be the sleep state, the handheld device 1 is locked.

The permission level of each application may be decided in advance by the handheld device 1 or may be set to be changed by the user.

The upper limit values and the lower limit values of the heart rate, the body temperature, and the blood pressure in the normal state may be decided in advance by the handheld device 1, but when the heart rate, the body temperature, and the blood pressure of the user are measured and learned, and the upper limit values and the lower limit values are obtained based on them, more accurate determination can be performed.

Commonly, in the sleep state, the heart rate, the blood pressure, and the body temperature decrease, and in the stress state, the heart rate and the blood pressure increase, but when the user measures and registers the heart rate, the body temperature, and the blood pressure in the sleep state and the stress state in advance, more accurate determination can be performed. Further, even when anyone else wears the handheld device 1 and causes the handheld device 1 to touch the finger of the authorized user and perform the fingerprint authentication, the heart rate, the body temperature, and the blood pressure are detected to be different from a tendency toward previous measured values of the authorized user, and in this case, the handheld device 1 may be locked.

The determination of the state of the user may be performed based on other dynamic biometric information such as the brain wave or the amount of sweating in addition to the heart rate, the blood pressure, and the body temperature.

Further, the terminal device 1 may perform the user authentication based on the dynamic biometric information obtained from a heart rate waveform, a brain wave, or the like instead of the static biometric information obtained from the fingerprint or the like.

As described above, according to the present embodiment, an application software start-up method of an information processing device includes performing user authentication based on static biometric information, determining a state of a user by comparing dynamic biometric information acquired from a body of the user with dynamic biometric information which is measured in advance, and limiting application software to be started according to the determined state of the user based on a permission level which is set to each application software in advance. Further, the information processing device is forcibly locked according to the determined state of the user.

Further, an information processing device includes a static biometric information acquisition unit that acquires static biometric information, a user authentication unit that performs user authentication by comparing the acquired static biometric information with static biometric information which is registered in advance, a dynamic biometric information acquisition unit that acquires dynamic biometric information from a body of the user, a state determination unit that determines a state of the user by comparing the acquired dynamic biometric information which is measured in advance, a lock control unit that unlocks the information processing device through the authentication of the user authentication unit, and an application start unit that starts application software which is selected by the user among a plurality of pieces of application software, wherein the application start unit limits application software to be started according to the state of the user determined by the state determination unit based on a permission level which is set to each application software in advance. Further, the lock control unit forcibly locks the information processing device according to the state of the user determined by the state determination unit.

Accordingly, in the present embodiment, it is determines whether or not the user is the authorized user based on the static biometric information, the state of the user is determined based on the dynamic biometric authentication, and the start of an application is limited stepwise according to the state of the user. Thus, when determination of the user is suspected, it is possible to limit the start of the specific application, for example, when it is against the user's will.

In FIG. 8, the same components as those in FIG. 3 which is a functional block diagram illustrating the handheld device 1 according to the first embodiment are denoted by the same reference numerals.

In FIG. 8, the components of the handheld device 2 are similar to the components obtained by excluding the dynamic biometric information acquisition unit 1120, the dynamic biometric information memory 1032, and the state determination unit 1012 from the components of FIG. 3, and thus a description of the same components as in FIG. 3 is omitted.

The functional blocks of the handheld device 2 are controlled by the control unit 2010. The control unit 2010 operates on the CPU 101 with which the handheld device 2 illustrated in FIG. 8 is equipped, includes the user authentication unit 1011, the lock control unit 1013, the application start unit 1014, and the like, and controls a memory 2030, the static biometric information acquisition unit 1110, the communication unit 1310, and the like based on an instruction given from the user interface 1040 such that the static biometric information is acquired, stored, and compared, the handheld device 2 is locked or unlocked, or an application starts.

The memory 2030 is configured with the memory 103 and the like which are illustrated in FIG. 7, and stores static biometric information 1031, an application 1033, a permission level table 1034 which is a table of levels at which applications are permitted to start, and the like, in addition to the program and various kinds of setting information for controlling the handheld device 2.

The communication with the handheld device 3 is performed through the short-range wireless communication device 133.

FIG. 9 is a functional block diagram illustrating the handheld device 3 according to the present embodiment. In FIG. 9, the same components as those in FIG. 3 which is a functional block diagram illustrating the handheld device 1 according to the first embodiment are denoted by the same reference numerals. In FIG. 9, the components of the handheld device 3 include the dynamic biometric information acquisition unit 1120, the dynamic biometric information memory 1032, and the state determination unit 1012 among the components of FIG. 3, and thus a detailed description thereof is omitted.

The functional blocks of the handheld device 3 are controlled by the control unit 3010. The control unit 3010 operates on the CPU 101 with which the handheld device 3 illustrated in FIG. 7 is equipped, includes the state determination unit 1012 and the like, and controls the dynamic biometric information acquisition unit 1120, a memory 3030, a communication unit 3310, and the like based on an instruction given from a user interface 3040 such that the dynamic biometric information is acquired, stored, transmitted, and displayed.

The user interface 3040 is configured with the operation device 104, the audio output device 142, the display device 152, and the like which are illustrated in FIG. 7, and presents the user with various kinds of information and transfers the instruction of the user to the control unit 3010.

The communication unit 3310 is configured with a short-range wireless communication device 333 and the like which are illustrated in FIG. 7 and performs communication with the handheld device 2.

The memory 3030 is configured with the memory 103 and the like which are illustrated in FIG. 7, and stores a program and various kinds of setting information for controlling the handheld device 3.

The state determination unit 1012 determines the state of the user by comparing the dynamic biometric information acquired through the dynamic biometric information acquisition unit 1120 when the handheld device 3 is used with the dynamic biometric information 1032, and transmits the state of the user to the handheld device 2 through the communication unit 3310.

For example, when the user is determined to be in the sleep state, the sleep state is transmitted to the handheld device 2 through the communication unit 3310, so that the handheld device 2 is locked. Further, an application to be started in the handheld device 2 is limited according to the state of the user. Further, when the user is determined to be in the normal state, all applications are set to enter the startable state, and when the user is determined to be in the stress state, applications that can be started are limited.

FIG. 10 is a flowchart illustrating an application permission operation of the handheld devices 2 and 3 of the present embodiment. This flowchart illustrates a process of performing the user authentication through the handheld device 2, checking the state of the user through the handheld device 3, and limiting an application to be started according to the state of the user.

First, the handheld device 2 detects the static biometric information, and performs the user authentication (S1001). For example, it is determined whether or not the user is the authorized user through the fingerprint authentication. In other words, a fingerprint pattern detected when the user touches the fingerprint sensor 211 with the finger is compared with the fingerprint pattern of the user registered in the memory 203, and it is determined whether or not the two fingerprints are identical to each other. When the two fingerprints are determined to be identical to each other, the handheld device 2 is unlocked (S1002), and the application of the permission level 1 is permitted to be started (S1003).

A display example of a screen of the handheld device 2 at this time is illustrated in FIG. 11A. The clock application, the web browser, the map application, the camera application, the weather forecast application, the music application, the calculator application, and the dictionary application are the applications of the permission level 1 and thus are in the startable state, and the other applications have a different icon color which indicates that they are in the non-startable state.

The user authentication may be performed through any other biometric authentication such as the vein authentication, the face authentication, the iris authentication, or the retina authentication, the unlocking operation may be performed by inputting a passcode, and a pattern lock may be released by the trajectory of the finger.

The handheld device 3 measures the heart rate through the heart rate sensor 312, measures the blood pressure through the blood pressure sensor 313, and measures the body temperature through the temperature sensor 314 (S1011).

The handheld device 2 requests the handheld device 3 to confirm the state of the user through a short-range wireless communication device 233 (S1012).

The handheld device 3 detects the dynamic biometric information, and determines the state of the user (S1013). For example, the state of the user is determined based on a result of measuring the heart rate, the blood pressure, and the body temperature. In other words, for example, when the heart rate, the blood pressure, and the body temperature measured through the heart rate sensor 312, the blood pressure sensor 313, the temperature sensor 114 of the handheld device 3 are equal to or less than the lower limit values in the normal state, the state of the user is determined to be the sleep state. Further, for example, when the heart rate and the blood pressure are equal to or larger than the upper limit values in the normal state, the state of the user is determined to be the stress state, and the state which corresponds to neither the sleep state nor the stress state is determined to be the normal state.

The handheld device 3 constantly acquires the dynamic biometric information, and performs, for example, the state determination based on the biometric information obtained for previous 30 seconds.

Then, the handheld device 3 transmits the state of the user to the handheld device 2 through the short-range wireless communication device 333 as a response (S1014).

The handheld device 2 switches the process according to whether or not the state of the user received through the short-range wireless communication device 233 is the sleep state (S1005). When the state of the user is determined to be the sleep state, the handheld device 2 is locked (S1010), and the process ends.

Further, even when the user does not wear the handheld device 3 or even when the terminal device 3 does not transmit the state of the user to the handheld device 2 as a response, the handheld device 2 is locked, and the process ends.

Steps S1006 to 1009 which are processes performed when the state of the user is determined not to be the sleep state are similar to steps S406 to 409 of FIG. 4 in the first embodiment, and thus a detailed description thereof is omitted.

A display example of the screen of the handheld device 2 when the applications of the permission levels 1 and 2 are permitted to be started in S1007 is illustrated in FIG. 11B. In addition to the fact that the applications of the permission level 1 are in the startable state, the schedule application, the mail application, the photo application, the telephone application, and the address book application are the applications of the permission level 2 and thus are in the startable state, and the other applications have a different icon color which indicates that they are in the non-startable state.

A display example of the screen of the handheld device 2 when all the applications of the permission levels 1 to 3 are permitted to be started in S1008 is illustrated in FIG. 11C. In addition to the fact that the applications of the permission levels 1 and 2 are in the startable state, the e-money application and the online banking application are the applications of the permission level 3 and thus are in the startable state, and it is indicated that all applications are in the startable state.

In the present embodiment, the handheld device 3 determines the state of the user, but the handheld device 3 may not determine the state of the user but transmit the measured values of the heart rate, the blood pressure, and the body temperature to the handheld device 2, and the handheld device 2 may determine the state of the user.

Further, the terminal device 2 may not perform the user authentication for the user, and the terminal device 3 may control whether or not the terminal device 2 is locked by performing the user authentication through the fingerprint authentication or the like and transmitting an authentication result to the terminal device 2. At this time, the terminal device 3 may perform the user authentication based on the dynamic biometric information obtained from the heart rate waveform, the brain wave, or the like rather than the static biometric information obtained from the fingerprint or the like.

In the present embodiment, the example in which the number of handheld devices is 2 has been described, but the number of handheld devices may be three or more, and the authentication function and the state determination function may be separated. In other words, the system including a plurality of handheld devices according to the present embodiment can be understood to be an application software start-up system including a plurality of information processing devices.

As described above, according to the present embodiment, an application software start-up method of an information processing device including a plurality of information processing devices includes performing, by at least one of the information processing devices, user authentication based on static biometric information of a body of a user, determining, by another information processing device, a state of a user by comparing dynamic biometric information acquired from the body of the user with dynamic biometric information which is measured in advance, and limiting application software to be started according to the determined state of the user based on a permission level which is set to each application software in advance.

Further, An application software start-up system includes first and second first information processing devices, the first information processing device includes a static biometric information acquisition unit that acquires static biometric information of a body, a user authentication unit that performs user authentication by comparing the acquired static biometric information with static biometric information which is registered in advance, a lock control unit that unlocks a handheld device through the authentication of the user authentication unit, an application start unit that starts application software which is selected by a user among a plurality of pieces of application software, and a first communication unit that receives a state of the user from the second information processing device, and the second information processing device includes a dynamic biometric information acquisition unit that acquires dynamic biometric information from the body of the user, a state determination unit that determines a state of the user by comparing the acquired dynamic biometric information which is measured in advance, and a second communication unit that transmits the determined state of the user to the first information processing device, wherein the application start unit limits application software to be started according to the state of the user received from the first communication unit based on a permission level which is set to each application software in advance.

Accordingly, in the present embodiment, the same effects as in the first embodiment are obtained, and when a plurality of handheld devices are registered in advance, and the user authentication function and the state determination function are distributed, each handheld device can be worn on a part of the body suitable for acquisition of each biometric information, and thus the handheld devices can be implemented in a form optimal for the respective functions.

Third Embodiment

FIG. 12 is a flowchart illustrating an application permission operation of the handheld device 1 of the present embodiment. In FIG. 12, steps S1201 to S1204 are similar to steps S401 to S404 of FIG. 4 in the first embodiment, and thus a description thereof is omitted.

In step S1205, the process is switched according to whether or not the state of the user is the sleep state. When the state of the user is determined to be the sleep state, the handheld device 1 is locked (S1210), and the process ends. When the state of the user is determined not to be the sleep state in step S1205, all the applications of the permission levels 1 to 3 are permitted to be started (S1208).

Here, the process is switched according to whether or not the state of the user is the stress state (S1206). When the state of the user is determined to be the stress stat, if the user selects the application of the permission level 3, a caution screen is displayed (S1221), and it is started only when the user confirms it. When the state of the user is determined not to be the stress state (determined to be the normal state), the caution screen is not displayed.

For example, when the application of the permission level 3 such as the e-money application or the online banking application is requested to be started, an application software start confirmation screen illustrated in FIG. 13 is displayed on the display device 152.

Steps S1209 to S1210 are similar to steps S409 to S410 of FIG. 4, and thus a description thereof is omitted.

The determination of the state of the user may be performed based on other dynamic biometric information such as the brain wave or the amount of sweating in addition to the heart rate, the blood pressure, and the body temperature.

In the present embodiment, the example in which the number of handheld devices is 1 has been described, but the number of handheld devices may be two or more, and the authentication function and the state determination function may be separated.

Through the above configuration, in the present embodiment, the same effects as in the first embodiment can be obtained, and since it is checked when a specific application is started according to the state of the user, for example, when determination of the user is suspected, it is possible to encourage reconsideration of the start of the specific application.

Fourth Embodiment

FIG. 14 is a flowchart illustrating an application permission operation of the handheld device 1 of the present embodiment. In FIG. 14, steps S1401 to S1403 are similar to steps S401 to S403 of FIG. 4, and thus a process of inputting a passcode (S1431 to S1433) is added.

First, the static biometric information is detected, and the user authentication is performed. The static biometric information acquisition unit 1110 acquires the static biometric information, and the user authentication unit 1011 performs the user authentication as to whether or not the acquired static biometric information is identical to the static biometric information 1031 which is registered in advance by comparing the acquired static biometric information with the static biometric information 1031 (S1401). For example, the fingerprint serving as the static biometric information is detected, the user authentication is performed, and when the detected fingerprint is determined to be identical to the registered fingerprint, the process proceeds to step S1431. The user authentication may be performed through any other biometric authentication such as the vein authentication, the face authentication, the iris authentication, or the retina authentication, in addition to the fingerprint authentication.

Then, the process is switched according to whether or not a sleep state detection log (which will be described later) in the memory 103 (S1431). When there is no sleep state detection log, the process proceeds to step S1402, and the lock control unit 1013 unlocks the handheld device 1, and the application start unit 1014 permits the start of the application of the permission level 1 (S1403).

When there is a sleep state detection log, the process proceeds to step S1432, a passcode input request screen illustrated in FIG. 15 is displayed, and the process proceeds to step S1402 when a passcode which is information other than the biometric information input from the user interface 1040 such as the operation device 104 or the audio input device 141 is identical to a passcode which is set in advance in step S1433. A pattern lock may be released by the trajectory of the finger instead of the passcode.

Steps S1404 to S1410 are similar to step S404 to S410 of FIG. 4, but a process of recording the sleep state detection log (S1434) is added.

When the state of the user is determined to be in the sleep state in step S1405, since it is suspected that anyone else causes the handheld device 1 to touch the finger of the user and perform the user authentication, in step S1434, position information which is a place in which the user authentication is performed is specified through the GPS receiver 121 and recorded as a log together with time information, the handheld device 1 is locked (S1410), and the process ends. The log is recorded in the memory 103.

Further, in step S1434, a warning may be displayed on the display device 152, a vibrator for an incoming call may be operated, a photograph or a video may be captured through the video input device 151, attached to an e-mail together with the log, and transmitted to an address which is designated in advance.

In the present embodiment, the example in which the number of handheld devices is 1 has been described, but the number of handheld devices may be two or more, and the authentication function and the state determination function may be separated.

Through the above configuration, in the present embodiment, the same effects as in the first embodiment can be obtained, and when the handheld device is likely to be operated by anyone else, a warning is displayed, a photograph is captured, and a log is recorded, and thus it can be expected that a family member or anyone else is prevented from furtively looking at an e-mail. Further, when the log is recorded, it is necessary to input the passcode in order to lock the handheld device, and thus it is possible to prevent anyone else from performing the unlocking operation.

Fifth Embodiment

FIG. 16 is a flowchart illustrating an application permission operation of the handheld device 1 of the present embodiment. In FIG. 16, steps S1601 to S1603 are similar to steps S401 to S403 of FIG. 4 in the first embodiment, and thus a process of inputting a passcode (S1631 to S1633) is added.

First, the static biometric information is detected, and the user authentication is performed. The static biometric information acquisition unit 1110 acquires the static biometric information, and the user authentication unit 1011 performs the user authentication as to whether or not the acquired static biometric information is identical to the static biometric information 1031 which is registered in advance by comparing the acquired static biometric information with the static biometric information 1031 (S1601). For example, the fingerprint serving as the static biometric information is detected, the user authentication is performed, and when the detected fingerprint is determined to be identical to the registered fingerprint, the process proceeds to step S1631. The user authentication may be performed through any other biometric authentication such as the vein authentication, the face authentication, the iris authentication, or the retina authentication, in addition to the fingerprint authentication.

Then, the process is switched according to whether or not there is a period of time in which it is unable to measure the dynamic biometric information after the handheld device 1 is previously unlocked (S1631). When there is not period of time in which it is unable to measure the dynamic biometric information, the process proceeds to step S1602, the lock control unit 1013 unlocks the handheld device 1, and the application start unit 1014 permits the start of the application of the permission level 1 (S1603).

When there is a period of time in which it is unable to measure the dynamic biometric information, since anyone else is likely to wear the handheld device 1, cause the handheld device 1 to touch the finger of the user, and perform the user authentication, the passcode input request screen illustrated in FIG. 15 is displayed on the handheld device 1, and when the input passcode is identical to the passcode which is set in advance in step S1633, the process proceeds to step S1602. A pattern lock may be released by the trajectory of the finger instead of the passcode.

Steps S1604 to S1610 are similar to step S404 to S410 of FIG. 4, and thus a description thereof is omitted.

In the present embodiment, the example in which the number of handheld devices is 1 has been described, but the number of handheld devices may be two or more, and the authentication function and the state determination function may be separated.

Through the above configuration, in the present embodiment, the same effects as in the first embodiment can be obtained, and when the handheld device is removed, it is necessary to input the passcode in order to unlock the handheld device next time, and thus it is possible to prevent anyone else from performing the unlocking operation.

Sixth Embodiment

FIG. 17 is a flowchart illustrating an application permission operation of the handheld device 1 of the present embodiment. In FIG. 17, steps S1701 to S1710 are similar to steps S401 to S410 of FIG. 4 in the first embodiment, and thus a process of switching an application according to a current position (S1741) is added.

In step S1706, the process is switched according to whether or not the state of the user is the stress state. When the state of the user is determined to be the stress state, the applications of the permission levels 1 and 2 are permitted to be started (S1707). When the state of the user is determined not to be the stress state (determined to be the normal state), the process is switched according to the current position of the handheld device 1 (S1741). The current position is specified through the GPS receiver 121, and when the current position is a predetermined position which is set in advance, all the applications of the permission levels 1 to 3 are permitted to be started (S1708). The predetermined position is, for example, the user's home or company or the like. When the current position is not a predetermined position which is set in advance, the applications of the permission levels 1 and 2 are permitted to be started (S1707).

Alternatively, all the applications of the permission levels 1 to 3 may be permitted to be started at a predetermined timing which is set in advance.

Alternatively, a face photograph of the user may be registered, and all the applications of the permission levels 1 to 3 may be permitted to be started when a face is captured through the video input device 151, and the user is recognized. Alternatively, all the applications of the permission levels 1 to 3 may be permitted to be started when the user is recognized, but anyone else around the user except the user is not recognized.

The determination of the state of the user may be performed based on other dynamic biometric information such as the brain wave or the amount of sweating in addition to the heart rate, the blood pressure, and the body temperature.

In the present embodiment, the example in which the number of handheld devices is 1 has been described, but the number of handheld devices may be two or more, and the authentication function and the state determination function may be separated.

Through the above configuration, in the present embodiment, the same effects as in the first embodiment can be obtained, and a specific application is permitted to be started when the user is at a safe position which is set in advance, and thus it is possible to limit the start of the application at a place which is not assumed by the user.
